Whether you are using a scroll saw or jigsaw, drill a large enough hole for blade in each vehicle window. Cut pieces out.

If you choose to, use a router to round over all your edges with a 1/8″ round over bit. Sand all edges smooth. You can see in the picture above the difference between the rough car and the routed/sanded car.

Drill holes for wheel axles and propellers for helicopter over each of the cross-hairs from template patterns. For the wheels you want the holes slightly LARGER than 1/4″ so your wheel axles will turn, for the propellers you want 1/4″ holes. Paint vehicles, let dry and lightly sand smooth.

Glue a wheel onto each dowel piece and set aside to dry.

For the propellers, rip a 3/8″-wide strip from your pine board, at least 8″-long. Cut a 5″-long piece and 2″-long piece from that. Drill a 1/4″ hole in the center of each.
